Ghost78, after your base bumper to bumper or powertrain warranties are over you also get a 12 month 12,000 mile warranty on replacement parts and labor when you pay for both from your dealer. If you buy the part from your dealer you get a warranty on the part and not the labor. Hopefully it doesn't come to that and your dealer can get this taken care of for you.

The oil cooler and any part of the drive train should be covered for 5 years or 100k miles. Am I mistaken?
